OTTAWA COUNTY, MI -- Ottawa County authorities have identified a man who drowned in July in the Grand River as a 40-year-old Grand Rapids man reported missing a month ago.

Authorities used dental records to identify 40-year-old Anthony O'neil Welch. His body was pulled from the Grand River in Georgetown Township on July 20 after kayakers near the 300 block of Baldwin Street notified sheriff's deputies.

Welch's family reported him missing to Grand Rapids Police on July 11, Ottawa County sheriff's Capt. Mark Bennett said Tuesday in a news release.

A forensic autopsy showed Welch accidentally drowned and there were no signs of traumatic injury.

Bennett earlier said the victim did not have identification on him, and investigators believe his body had been in the water for several days.

Sheriff's investigators continue to work with Grand Rapids Police. Anyone with information about Welch's death is asked to call Silent Observer at 1-877-88-SILENT.
